Many models in which the object under study loses all its mass have appeared in
the literature. No doubt, the most eminent examples are the models for evaporating black holes
and for evaporating stars. Here we describe a semiclassical study of these evaporating models
centered on the evaporating event itself. We pay special attention to the evaporating models as
a means of avoiding singularities during the collapse. In case of any pre-existing non-spacelike
curvature singularity, we show that these models tend to evaporate it.
